Senator Jeanne Shaheen, a Democrat from New Hampshire, has announced she will not seek re-election in 2026, a decision that could complicate her party’s efforts to regain a Senate majority, reports The New York Times.

Shaheen's decision not to run again deals a significant blow to Democrats who were already facing a difficult path to reclaiming the Senate majority.

N.H., serves on the armed services committee and was the first-ever woman to chair the Senate Foreign Relations Committee.
